We have two machines each with 128G, and we had to turn off swap due to the kswapd going crazy and constantly trying to use swap it didn't need. Brought our production dbs to a crawl. My recommendation is to have enough memory to not ever need swap space if you can afford it. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
